PT8A2651 Overview
The PT8A2651 is a CMOS LSI chip designed for automatic PIR lamp control. The chip is equipped with operational amplifiers, a parator, timer, a zero crossing detector, control circuit, a voltage regulator, a system oscillator, and an output timing oscillator. Its PIR sensor detects infrared power variations induced by the motion of a human body and transforms it to a voltage variation.
